The 90-minute documentary, “I Am Britney Jean” — a nod to the title of Spears’ upcoming album, “Britney Jean” — will premiere Dec. 22 at 8 p.m., with a rebroadcast at 9:30 p.m.

Directed by Fenton Bailey and Randy Barbato (“Inside Deep Throat”), the documentary will follow Spears as she preps for “Britney: Piece of Me,” her two-year residency at Vegas’ Planet Hollywood Resort & Casino.

“With her new album, ‘Britney Jean,’ dropping December 3rd, and rehearsals slated to begin December 10th in Las Vegas, Britney is going to be hard at work preparing for her most elaborate production to date,” E! said in a statement announcing the project. “Viewers will get a rare glimpse inside Spears’ life at an integral moment, as she finishes writing and recording her most personal album to date, all while producing and co-directing her first ever Las Vegas Residency. Spears will also open up about her personal and professional life in her most candid and revealing interviews ever.”

World of Wonder (“RuPaul’s Drag Race,” “Million Dollar Listing”) is producing the documentary.
